| Marbling scores assigned by graders (GRADE_BMS) are comprehensively evaluated, considering the ratio of marbling area to ribeye area (FATPER), coarseness of marbling (COARSE), shape of marbling (SHAPE), dispersion of marbling particles in the ribeye area (DISP), etc. The purposes of this study were to calculate FATPER, COARSE, SHAPE, and DISP numerically by image analysis method and to estimate genetic parameters for meat quality traits involving these image analysis traits. Digital images of the ribeye area from the 6th to 7th rib cross section of 706 Japanese Black steers at the progeny testing. Genetic parameters for carcass traits assigned by graders were estimated with an animal model using the multitrait REML program by canonical transformation.... |
